Phil Costabile

Senior Vice President


404- 834-6571


Phil leads Atlanta’s tenant rep team, a similar role to the position he held with Southsouce from 2021 until the boutique brokerage merged with Foundry Commercial in 2023. Phil worked at JLL in Atlanta before joining Southsource. While there, he acquired experience in tenant representation, portfolio management, real estate investments, and lease dispositions.

Phil is particularly experienced in advising professional services companies, likely because he is perceptive and inquisitive, catching all manner of details and minutia around the goals of his clients. He has a deep appreciation for the experiential qualities of neighborhoods and buildings, and how those add value for clients. It’s been said that Phil can find the bright side of a cave, and it’s impossible to talk about his work without mentioning his relentless positivity.

Phil is from Pennsylvania, and since 2014 has lived in Atlanta’s Buckhead with his wife, Baxley, and their two sons. He enjoys golf, running, chasing his kids around, live-band karaoke, and any sporting event involving a pro sports team from Philadelphia.
